In a medium mixing bowl, combine shredded cabbage, diced mango, sliced bell pepper, grated carrot, chopped cilantro, and sliced green onions. Toss well to combine.
In another small bowl, whisk together lime juice, fish sauce, honey, sesame oil, grated ginger, and minced chili (if using) to create the dressing.
Pour the dressing over the mixed salad and toss again until everything is evenly coated.
If using, sprinkle the crushed peanuts on top before serving for added crunch.
Serve immediately or let it chill in the refrigerator for 10-15 minutes to enhance the flavors.
